Convert servers to using _DEPENDENCIES to ensure proper rebuilds.

This cleans up server Makefile.ams a little bit, but also means that people
messing with configure.ac need to be careful with whether they put libraries
in the _LIBS or _SYS_LIBS targets.  Hopefully the comment in configure.ac will
clarify the issues.
